- the ceiling system further comprising a plurality of clips, each of the clips having two ears depending upwardly from an upper horizontal member, a back wall depending downwardly from the upper horizontal surface and a panel engaging member connected to the back wall.
- the ceiling system has a plurality of panels having a generally rectangular shape, the panels having major edges and minor edges and an outward facing surface, said panels having a slit on the major edge, wherein the panel engagement member of the clip is completely received within the slit and the back wall of the clip abuts an edge of the panel; and wherein the ears of the clip engage with the edges of the perpendicular portion of the T-bar and secure the clip to the T-bar, and wherein each panel is attached by the clips to at least two T-bars.
- FIGS. 1 a and 1 b show perspective and side views of an embodiment of a clip for use in a ceiling system. Like numerals will be used to denote the same elements in FIGS. 1 a and 1 b .
- the clip 1 is provided with two ears 2 .
- the ears 2 depend upwardly from upper horizontal member 3 .
- the ears 2 engage with the edges of a T-bar and secure the clip to the T-bar.
- the T-bar rides against the upper horizontal member 3 when the clip is assembled on the T-bar.
- the back wall 4 is also visible in FIG. 1 a .
- back wall 4 depends downwardly from upper horizontal surface 3 and connects the upper horizontal surface to the panel engaging member 5 .
- the panel engagement member 5 is received in a slit in a panel for the ceiling system. When assembled, the panel engagement member 5 is completely received within the slit in the panel and the back wall 4 abuts the edge of the panel.
- FIGS. 2 a and 2 b show various views of an embodiment of a panel for a ceiling system.
- the panel 20 takes a generally rectangular shape, though one of ordinary skill in the art will appreciate that the shape of the panel can be varied depending on the configuration required for a given application of the ceiling system.
- the panel has a major edges 21 a and 21 b and minor edges 22 a and 22 b and an outward facing surface 23 .
- the panel 20 may be constructed of polyester fiberboard, and more particularly a 12 mm Class “A” polyester fiberboard. The outward facing surface 23 of this polyester fiberboard may then be covered with a wood grain embossed PVC film 26 . Referring now to the cross-sectional view of FIG.
- slits 24 are provided in the major edges, 21 a and 21 b of the panel.
- the slit 24 is provided to accommodate the panel engagement member 5 of the clip 1 as discussed above.
- Wood grain PVC film 26 is disposed on the outward facing, suffice 23 .
- No PVC film is provided on or below the slit 24 on edges 21 a and 21 b .
- No PVC film is disposed on the back side 25 of the panel, as this portion of the panel will not be visible when the panel is installed.
- FIG. 2 c is an enlarged view of the encircled area labelled “C” in FIG. 2 a .
- the outward facing surface 23 of the panel 20 which is covered in the wood grain embossed PVC film 26 , has a plurality of microperforations 27 formed in the PVC film 26 .
- the microperforations 27 have a circular shape and a diameter in the range of 0.05 to 1 mm and more preferably in the range of 0.25 to 0.75 mm. It should be further appreciated that while FIG.
- FIG. 2 c shows only the section denoted “C” in FIG. 2 a , the microperforations 27 formed in the PVC film 26 cover the entire outward facing surface 23 of the panel 20 .
- the microperforations 27 extend all the way through the PVC film 26 .
- FIG. 3 shows an embodiment of a clip for a ceiling system engaged with a T-bar.
- the assembly 30 shown in FIG. 3 has a T-bar 31 , which has upright portion 32 and perpendicular portion 33 .
- the T-bar is attached to rafters or other structural members defining a roof of a building as would be understood by one of ordinary skill in the art.
- the ears 2 of clip 1 engage with the perpendicular portion 33 of the T-bar 31 .
- the underside surface (not shown) of perpendicular portion 33 is in contact with the upper horizontal member 3 of the clip 1 .
- FIGS. 4 a and 4 b show partially exploded and assembled views of the T-bar, clip and panel for the ceiling system.
- the T-bar 31 with upright portion 32 and the perpendicular portion 33 are shown.
